Abstract

With the rapidly increasing impact of the Internet, the development of appropriate intrusion detection systems (IDS) gains more and more importance. This article presents a performance comparison of four neural and fuzzy paradigms (multilayer perceptrons, radial basis function networks, NEFCLASS systems, and classifying fuzzy-k-means) applied to misuse detection on the basis of TCP and IP header information. As an example, four different attacks (Nmap, Portsweep, Dict, Back) will be detected utilising evaluation data provided by the Defense Advanced Research Projects Agency (DARPA). The best overall classification results (99.42%) can be achieved with radial basis function networks, which model hyperspherical clusters in the feature space.
